2022-01-17widening_mul, i386: Improve spaceship expansion on x86 [PR103973]Jakub Jelinek1-25/+0
C++20: #include <compare> auto cmp4way(double a, double b) { return a <=> b; } expands to: ucomisd %xmm1, %xmm0 jp .L8 movl $0, %eax jne .L8 .L2: ret .p2align 4,,10 .p2align 3 .L8: comisd %xmm0, %xmm1 movl $-1, %eax ja .L2 ucomisd %xmm1, %xmm0 setbe %al addl $1, %eax ret That is 3 comparisons of the same operands. The following patch improves it to just one comparison: comisd %xmm1, %xmm0 jp .L4 seta %al movl $0, %edx leal -1(%rax,%rax), %eax cmove %edx, %eax ret .L4: movl $2, %eax ret While a <=> b expands to a == b ? 0 : a < b ? -1 : a > b ? 1 : 2 where the first comparison is equality and this shouldn't raise exceptions on qNaN operands, if the operands aren't equal (which includes unordered cases), then it immediately performs < or > comparison and that raises exceptions even on qNaNs, so we can just perform a single comparison that raises exceptions on qNaN. As the 4 different cases are encoded as ZF CF PF 1 1 1 a unordered b 0 0 0 a > b 0 1 0 a < b 1 0 0 a == b we can emit optimal sequence of comparions, first jp for the unordered case, then je for the == case and finally jb for the < case. The patch pattern recognizes spaceship-like comparisons during widening_mul if the spaceship optab is implemented, and replaces those comparisons with comparisons of .SPACESHIP ifn which returns -1/0/1/2 based on the comparison. This seems to work well both for the case of just returning the -1/0/1/2 (when we have just a common successor with a PHI) or when the different cases are handled with various other basic blocks. The testcases cover both of those cases, the latter with different function calls in those. 2022-01-17 Jakub Jelinek <jakub@redhat.com> PR target/103973 * tree-cfg.h (cond_only_block_p): Declare. * tree-ssa-phiopt.c (cond_only_block_p): Move function to ... * tree-cfg.c (cond_only_block_p): ... here.

Before match-and-simplify was used in phiot, the location of the new stamtents were all of that of the conditional, this adds that back as I did not realize gimple_simplify didn't do that for you. OK? Bootstrapped and tested on x86_64 with no regressions. gcc/ChangeLog: * tree-ssa-phiopt.c (gimple_simplify_phiopt): Annotate the new sequence with the location of the conditional statement.

Consider the following C++ testcase: #include <compare> #define A __attribute__((noipa)) A bool f5 (double i, double j) { auto c = i <=> j; return c >= 0; } This turns into a comparison against chars, on systems where chars are signed the pattern inserts an unsigned convert such that it's able to do the transformation. i.e.: # RANGE [-1, 2] # c$_M_value_22 = PHI <-1(3), 0(2), 2(5), 1(4)> # RANGE ~[3, 254] _11 = (unsigned char) c$_M_value_22; _19 = _11 <= 1; # .MEM_24 = VDEF <.MEM_6(D)> D.10434 ={v} {CLOBBER}; # .MEM_14 = VDEF <.MEM_24> D.10407 ={v} {CLOBBER}; # VUSE <.MEM_14> return _19; instead of: # RANGE [-1, 2] # c$_M_value_5 = PHI <-1(3), 0(2), 2(5), 1(4)> # RANGE [-2, 2] _3 = c$_M_value_5 & -2; _19 = _3 == 0; # .MEM_24 = VDEF <.MEM_6(D)> D.10440 ={v} {CLOBBER}; # .MEM_14 = VDEF <.MEM_24> D.10413 ={v} {CLOBBER}; # VUSE <.MEM_14> return _19; This causes much worse codegen under -ffast-math due to phiops no longer recognizing the pattern. It turns out that phiopts spaceship_replacement is looking for the exact form that was just changed. The comments seems to suggest this code only checks for (res & ~1) == 0 but the implementation seems to suggest it's broader. As such I added a case to check to see if the value comparison we found is a type cast. and strips away the type cast and continues. In match.pd the typecasts are only added for signed comparisons to == 0 and != 0 which are then rewritten into comparisons with 1. As such I only check for 1 and LE and GT, which is what match.pd would have rewritten it to. This fixes the regression but this is not code I 100% understand, since I don't really know the semantics of the spaceship operator so would appreciate an extra look. gcc/ChangeLog: * tree-ssa-phiopt.c (spaceship_replacement): Handle new canonical codegen.

2021-11-16tree-optimization/102880 - make PHI-OPT recognize more CFGsRichard Biener1-30/+41
This allows extra edges into the middle BB for the PHI-OPT transforms using replace_phi_edge_with_variable that do not end up moving stmts from that middle BB. This avoids regressing gcc.dg/tree-ssa/ssa-hoist-4.c with the actual fix for PR102880 where CFG cleanup has the choice to remove two forwarders and picks "the wrong" leading to if (a > b) / /\ / / <BB> / | # PHI <a, b> rather than if (a > b) | /\ | <BB> \ | / \ | # PHI <a, b, b> but it's relatively straight-forward to support extra edges into the middle-BB in paths ending in replace_phi_edge_with_variable and that do not require moving stmts. That's because we really only want to remove the edge from the condition to the middle BB. Of course actually doing that means updating dominators in non-trival ways which is why I kept the original code for the single edge case and simply defer to CFG cleanup by adjusting the condition for the complicated case. The testcase needs to be a GIMPLE one since it's quite unreliable to produce the desired CFG. 2021-11-15 Richard Biener <rguenther@suse.de> PR tree-optimization/102880 * tree-ssa-phiopt.c (tree_ssa_phiopt_worker): Push single_pred (bb1) condition to places that really need it.

2021-11-09Introduce build_debug_expr_declMartin Jambor1-8/+2
This patch introduces a helper function build_debug_expr_decl to build DEBUG_EXPR_DECL tree nodes in the most common way and replaces with a call of this function all code pieces which build such a DECL itself and sets its mode to the TYPE_MODE of its type. There still remain 11 instances of open-coded creation of a DEBUG_EXPR_DECL which set the mode of the DECL to something else. It would probably be a good idea to figure out that has any effect and if not, convert them to calls of build_debug_expr_decl too. But this patch deliberately does not introduce any functional changes. gcc/ChangeLog: 2021-11-08 Martin Jambor <mjambor@suse.cz> * tree.h (build_debug_expr_decl): Declare. * tree.c (build_debug_expr_decl): New function. * cfgexpand.c (avoid_deep_ter_for_debug): Use build_debug_expr_decl instead of building a DEBUG_EXPR_DECL. * ipa-param-manipulation.c (ipa_param_body_adjustments::prepare_debug_expressions): Likewise. * omp-simd-clone.c (ipa_simd_modify_stmt_ops): Likewise. * tree-ssa-ccp.c (optimize_atomic_bit_test_and): Likewise. * tree-ssa-phiopt.c (spaceship_replacement): Likewise. * tree-ssa-reassoc.c (make_new_ssa_for_def): Likewise.

2021-08-02Optimize x ? bswap(x) : 0 in tree-ssa-phioptRoger Sayle1-11/+26
Many thanks again to Jakub Jelinek for a speedy fix for PR 101642. Interestingly, that test case "bswap16(x) ? : x" also reveals a missed optimization opportunity. The resulting "x ? bswap(x) : 0" can be further simplified to just bswap(x). Conveniently, tree-ssa-phiopt.c already recognizes/optimizes the related "x ? popcount(x) : 0", so this patch simply makes that transformation make general, additionally handling bswap, parity, ffs and clrsb. All of the required infrastructure is already present thanks to Jakub previously adding support for clz/ctz. To reflect this generalization, the name of the function is changed from cond_removal_in_popcount_clz_ctz_pattern to the hopefully equally descriptive cond_removal_in_builtin_zero_pattern. 2021-08-02 Roger Sayle <roger@nextmovesoftware.com> gcc/ChangeLog * tree-ssa-phiopt.c (cond_removal_in_builtin_zero_pattern): Renamed from cond_removal_in_popcount_clz_ctz_pattern.

2021-07-09Improve early simplify and match for phioptAndrew Pinski1-13/+49
Previously the idea was gimple_simplify_phiopt would call resimplify with a NULL sequence but that sometimes fails even if there was only one statement produced. The cases where it fails is when there are two simplifications happen. In the case of the min/max production, the first simplifcation produces: (convert (min @1 @2)) And then the convert is removed by a second one. The Min statement will be in the sequence while the op will be a SSA name. This was rejected before as could not produce something in the sequence. So this patch changes the way resimplify is called to always passing a pointer to the sequence and then decide based on if op is a SSA_NAME or not. OK? Bootstrapped and tested on x86_64-linux-gnu. gcc/ChangeLog: * tree-ssa-phiopt.c (phiopt_early_allow): Change arguments to take sequence and gimple_match_op. Accept the case where op is a SSA_NAME and one statement in the sequence. Also allow constants. (gimple_simplify_phiopt): Always pass a sequence to resimplify. Update call to phiopt_early_allow.

So the problem here is that replace_phi_edge_with_variable will copy range information to a already (not newly) defined ssa name. This causes wrong code later on. This fixes the problem by require the new ssa name to be defined in the same bb as the conditional that is about to be deleted. OK? Bootstrapped and tested on x86_64-linux-gnu with no regressions.

I had missed this when wrote the patch which allowed the gimple to be moved from inside the conditional as it. It was also missed in the review. Anyways the range information needs to be reset for the moved gimple as it was under a conditional and the flow has changed to be unconditional. I have not seen any testcase in the wild that produces wrong code yet which is why there is no testcase but this is similar to what the other code in phiopt does so after moving those to match, there might be some.

Here are 3 improvements that make it match: 1) as mentioned in the comment above spaceship_replacement, for strong_ordering, we are pattern matching something like: x == y ? 0 : x < y ? -1 : 1; and for partial_ordering x == y ? 0 : x < y ? -1 : x > y ? 1 : 2; but given the == comparison done first and the other comparisons only if == was false, we actually don't care if the other comparisons are < vs. <= (or > vs. >=), provided the operands of the comparison are the same; we know == is false when doing those and < vs. <= or > vs. >= have the same behavior for NaNs too 2) when y is an integral constant, we should treat x < 5 equivalently to x <= 4 etc. 3) the code punted if cond2_phi_edge wasn't a EDGE_TRUE_VALUE edge, but as the new IL shows, that isn't really needed; given 1) that > and >= are equivalent in the code, any of swapping the comparison operands, changing L[TE]_EXPR to G[TE]_EXPR or vice versa or swapping the EDGE_TRUE_VALUE / EDGE_FALSE_VALUE bits on the edges reverses one of the two comparisons 2021-05-21 Jakub Jelinek <jakub@redhat.com> PR tree-optimization/94589 * tree-ssa-phiopt.c (spaceship_replacement): For integral rhs1 and rhs2, treat x <= 4 equivalently to x < 5 etc. In cmp1 and cmp2 (if not the same as cmp3) treat <= the same as < and >= the same as >.

2021-05-18phiopt: Optimize partial_ordering spaceship >= 0 -ffinite-math-only [PR94589]Jakub Jelinek1-9/+63
As mentioned earlier, spaceship_replacement didn't optimize partial_ordering >= 0 comparisons, because the possible values are -1, 0, 1, 2 and the >= comparison is implemented as (res & 1) == res to choose the 0 and 1 cases from that. As we optimize that only with -ffinite-math-only, the 2 case is assumed not to happen and my earlier match.pd change optimizes (res & 1) == res into (res & ~1) == 0, so this patch pattern matches that case and handles it like res >= 0. 2021-05-18 Jakub Jelinek <jakub@redhat.com> PR tree-optimization/94589 * tree-ssa-phiopt.c (spaceship_replacement): Pattern match phi result used in (res & ~1) == 0 comparison as res >= 0 as res == 2 would be UB with -ffinite-math-only. * g++.dg/opt/pr94589-2.C: Adjust scan-tree-dump count from 14 to 12.

2021-05-06phiopt: Optimize (x <=> y) cmp z [PR94589]Jakub Jelinek1-0/+424
genericize_spaceship genericizes i <=> j to approximately ({ int c; if (i == j) c = 0; else if (i < j) c = -1; else c = 1; c; }) for strong ordering and ({ int c; if (i == j) c = 0; else if (i < j) c = -1; else if (i > j) c = 1; else c = 2; c; }) for partial ordering. The C++ standard supports then == or != comparisons of that against strong/partial ordering enums, or </<=/==/!=/>/>= comparisons of <=> result against literal 0. In some cases we already optimize that but in many cases we keep performing all the 2 or 3 comparisons, compute the spaceship value and then compare that. The following patch recognizes those patterns if the <=> operands are integral types or floating point (the latter only for -ffast-math) and optimizes it to the single comparison that is needed (plus adds debug stmts if needed for the spaceship result). There is one thing I'd like to address in a follow-up: the pr94589-2.C testcase should be matching just 12 times each, but runs into operator>=(partial_ordering, unspecified) being defined as (_M_value&1)==_M_value rather than _M_value>=0. When not honoring NaNs, the 2 case should be unreachable and so (_M_value&1)==_M_value is then equivalent to _M_value>=0, but is not a single use but two uses. I'll need to pattern match that case specially. 2021-05-06 Jakub Jelinek <jakub@redhat.com> PR tree-optimization/94589 * tree-ssa-phiopt.c (tree_ssa_phiopt_worker): Call spaceship_replacement.

2021-03-09phiopt: Fix up conditional_replacement [PR99305]Jakub Jelinek1-3/+3
Before my PR97690 changes, conditional_replacement would not set neg when the nonzero arg was boolean true. I've simplified the testing, so that it first finds the zero argument and then checks the other argument for all the handled cases (1, -1 and 1 << X, where the last case is what the patch added support for). But, unfortunately I've placed the integer_all_onesp test first. For unsigned precision 1 types such as bool integer_all_onesp, integer_onep and integer_pow2p can all be true and the code set neg to true in that case, which is undesirable. The following patch tests integer_pow2p first (which is trivially true for integer_onep too and tree_log2 in that case gives shift == 0) and only if that isn't the case, integer_all_onesp. 2021-03-09 Jakub Jelinek <jakub@redhat.com> PR tree-optimization/99305 * tree-ssa-phiopt.c (conditional_replacement): Test integer_pow2p before integer_all_onesp instead of vice versa. * g++.dg/opt/pr99305.C: New test.

While we have at the RTL level noce_try_ifelse_collapse combined with simplify_cond_clz_ctz, that optimization doesn't always trigger because e.g. on powerpc there is an define_insn to compare a reg against zero and copy that register to another one and so we end up with a different pseudo in the simplify_cond_clz_ctz test and punt. For targets that define C?Z_DEFINED_VALUE_AT_ZERO to 2 for certain modes, we can optimize it already in phiopt though, just need to ensure that we transform the __builtin_c?z* calls into .C?Z ifns because my recent VRP changes codified that the builtin calls are always undefined at zero, while ifns honor C?Z_DEFINED_VALUE_AT_ZERO equal to 2. And, in phiopt we already have popcount handling that does pretty much the same thing, except for always using a zero value rather than the one set by C?Z_DEFINED_VALUE_AT_ZERO.

2020-04-25cselim: Don't assume it is safe to cstore replace a store to a local ↵Jakub Jelinek1-2/+6
variable with unknown offset [PR94734] As the new testcase shows, it is not safe to assume we can optimize a conditional store into an automatic non-addressable var, we can do it only if we can prove that the unconditional load or store actually will not be outside of the boundaries of the variable. If the offset and size are constant, we can, but this is already all checked in !tree_could_trap_p, otherwise we really need to check for a dominating unconditional store, or for the specific case of automatic non-addressable variables, it is enough if there is a dominating load (that is what those 4 testcases have). tree-ssa-phiopt.c has some infrastructure for this already, see the add_or_mark_expr method etc., but right now it handles only MEM_REFs with SSA_NAME first operand and some integral offset. So, I think it can be for GCC11 extended to handle other memory references, possibly up to just doing get_inner_reference and hasing based on the base, offset expressions and bit_offset and bit_size, and have also a special case that for !TREE_ADDRESSABLE automatic variables it could ignore whether something is a load or store because the local stack should be always writable. But it feels way too dangerous to do this this late for GCC10, so this patch just restricts the optimization to the safe case (where lhs doesn't trap), and on Richi's request also ignores TREE_ADDRESSABLE bit if flag_store_data_races, because my understanding the reason for TREE_ADDRESSABLE check is that we want to avoid introducing store data races (if address of an automatic var escapes, some other thread could be accessing it concurrently). 2020-04-25 Jakub Jelinek <jakub@redhat.com> Richard Biener <rguenther@suse.de> PR tree-optimization/94734 PR tree-optimization/89430 * tree-ssa-phiopt.c: Include tree-eh.h.
